How do I convert TIFF to PNG?

Add your TIFF file to the upload area above, then press Convert. The PNG file downloads straight to your device. You do not need an account, and there is no watermark.

Are my files uploaded to a server?

No. This conversion runs entirely inside your browser using WebAssembly, so the file never leaves your device — you can even disconnect from the internet after the page loads and it will still work.

Does converting to PNG reduce quality?

No. PNG is a lossless format, so the conversion preserves exactly what is in your TIFF file. Note that it cannot recover detail that was already discarded when the TIFF was first created — a lossless container does not undo earlier compression.

How large a file can I convert?

Up to 120 MB per file for this conversion. Because the work happens in your browser, the practical limit is your device's memory — larger files work on a desktop with plenty of RAM and may fail on an older phone.

Can I convert several files at once?

Yes. Add as many as you like and press Convert All. Each file is processed independently, so one failure does not stop the rest, and you can download everything together as a ZIP.

Can I use this on my phone?

Yes. FileTools360 works in mobile browsers on iOS and Android, including choosing files straight from your camera roll. Very large videos may run out of memory on a phone — those are better converted on a laptop.

TIFF and PNG explained

TIFF is a flexible container used in print, publishing and archiving. It can hold multiple pages, layers, and a variety of compression schemes including none at all, which is why TIFF files vary enormously in size.

PNG is a lossless raster format built to replace GIF. It stores every pixel exactly as given and supports a full 8-bit alpha channel, which means genuine partial transparency rather than the single transparent colour GIF offers.

Where TIFF files come from: Scanners, professional photography workflows, and print production.
Where PNG is used: Screenshots, exported logos and UI assets, and anything designed rather than photographed.

TIFF vs PNG

The two formats solve different problems, which is why converting between them involves trade-offs rather than a straight upgrade.

TIFF compared with PNG
Property	Source	Target
Compression	Lossy or lossless	Lossless
Transparency	Yes	Yes
Animation	No	No
Introduced	1986	1996
Browser support	Professional tools yes, web browsers no.	Universally supported.

TIFF is stronger at: Lossless, with optional compression. Supports multiple pages in one file. Handles CMYK and high bit depths for print.
PNG is stronger at: Completely lossless — re-saving never degrades the image. Full alpha transparency, including soft edges and shadows. Sharp text and hard edges stay sharp.

Why convert TIFF to PNG?

People make this switch when they run into the limits of TIFF: anything involving the web or casual sharing. PNG is the better fit when the image has transparency, text, screenshots, logos, or you need an exact pixel-for-pixel copy.

TIFF limitations that prompt the switch: No browser support at all. Large files. The format's flexibility means some TIFFs will not open in some readers.
What you give up: Much larger than JPEG or WebP for photographic content. No animation in practice (APNG exists but support is inconsistent).

Does converting TIFF to PNG reduce quality?

Both formats store the content without discarding data, so this conversion preserves it exactly. The file size may change because the two formats compress differently, but the content itself is unaffected.

Converting a JPEG to PNG does not improve its quality. It freezes the image exactly as it already is, artefacts included, in a larger file.
